SPECIFICATION forming part of Letters Patent No. 492,121, dated February 21, 1893.

Application filed September Z2, 1891. Serial No. 406,471. (No model.)

To all whom it may concern:

Be it known that I, AMBRosn W. STRAUB,a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain newand usefullmprovements in MetallicRailway Ties, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to metallic railway ties i and consists of certain improvements, which are fully set forth in the following specification andthe accompanying drawings which form part thereof.

The object of my invention is to provide a light but strong and durable tie and one that can be economicallyand readily man ufactured and, therefore, serve an important purpose in railway construction. To accomplish this object I employ the structuralprinciple of the angle iron of commerce, and like the said iron the body of my tie can be rolled and manufactured in a rolling mill, provision being made by heavy rolls. of'a suitable shape to give the desired forml yto thetie. I could also bend the flanges from a sheet'of plate metal. I thus gain great strength and stiffness and the amount-of metal rexuired-in' each individual tieis reduced toa minimum. The oost is, therefore, also 4greatly reduced, as will be readily understood. To guard against the possibility of displacement in any direction I extend one angle, iiange or anchor upward from the body of the tie, and project one flange or anchor downward from the body of the tie. These flanges arermly embedded in the ballast. I can also provide my depending flange, for the purpose of making the tie more secure in the ballast, with lateral, longitudinal horizontal strips. They can be'eith'er bent from and made integral with the depen-'ding flange, or riveted thereto. "s .f

In order to anticipate and counteract any tendency to lateral movement or displacement of the'tie, I mortise the center of the tie bed plate and bend a portion of the bed plate metal upward and a portion downward. I thus get two transverse flanges, each of which is firmly implanted in the ballast. While I show in the drawings the tie as mortised in the center and project one part of the metal liberated upward and one part down- .rivets, bolts or any effectual means.

ward, I desire it understood I do not limit myself to this specific construction. I could also bolt or rivet a transverse angle plate on the bed plate of the tie as a full equivalent. I, however, prefer the mortise in practice. The rails are held in position on the tie by transverse supports to which they are secured by These supports are in turn secured to the bed plate of the tie.

In the' drawings Figure I is a perspective view of -my improved metallic tie in which all the features are clearly shown. Fig. Il is a transverse view on the track of a railway having my improved tie. Two forms of' supports are shown for the rails. Form A A in section; form BB in elevation. Fig. III is aside elevation of arail supported by my improved tie, in which the manner of embedding the tie in the ballast is clearly shown.

R is the bed plate of my improved tie.

G is the upward extending flange or anchor. H is the depending anchor or flange. These flanges are firmly implanted in the ballast. This downward extending flange is an important. feature of my invention, for by itsA 4their function is to prevent lateral displacement. y

In Fig. I I show a perspective view of the rail clamps, 5., e, the'means I employ for holding the rails to the tie. A A shows two transverse clamping. pieces formed from heavy sheet `metal and consist of a right angular bent metallic piece with the upper end bent over. 4'-I`o`f'c'lam`p and-hold the rail, a hole is punched in the plates. v

D, Figs. I and II, is a section of a block of wood incased by the clamps, A. A. The rail, C C, Fig. II, rests on this wood, and the clamps,

IOO

A A., engage the lower llanges of the rail and hold it rmly in place.

e', Fig. II, is abolt which passes through the angle plates and the wood and holds them firmly together.

f, Fig. II, is a bolt which passes through the transverse angular rail clamps A. A. and B B and holds them firmly to the bed plate R or body of the tie.

In Fig. II at the angular rail clamps A. A.y

the depending flange H H is shown as broken in order to clearly show the method of securing the said clamps to the body R.

B B, Fig. II, shows a ditte rent method of su pporting the rails. In this construction I dispense with the wooden rail supports and instead provide clamps of a shape'suitable for both clamping and supporting the rails. The shape of these clamps is shown by B B Fig.' II and a modified shape is atB Fig; I. In Fig; II` these rail clamping supports B B are slightly curved, by this constructionand the employment of heavy sheet steel in their manufac` ture, I obtain a slight spring which on the passage of a train will relieve the same from a certain amount ot' jar and to some extent prolong the life of the rolling stock and be a source of'comt'ort to passengers.

O O, Fig. III, shows the ballastand the man# ner in which the ties are rmlyheld therein.-

An important advantage in extending one longitudinal flange upward and one'down ward and making the tie Z shaped places the major portion ot` the tie deep under the ballast where, in case a train should be derailed it-would receive the least injury. By making my tieof the above described shape I gain the greatest possible amount of anchorage. I keep the body of the ballast at all times intact, both above and below the body of the tie. This possesses a decided advantage over tiesmade heretofore having double upward extending and downward extending flanges. Those ties possess the disadvantage ot' boxing a portion ot' the ballast, above and below the bed plate; The tendency of my tie to rock or crawl inthe ballast is reduced to a minimum and is greatly relieved from this weakness of the double flanged ties. On heavy grades and curves the frictional anchorage of my tie is much superior to the old doubled flanged ties. The S shaped rail supports clamp the rail firmly and when rails are joined at the end of these supports, fish plates can be dispensed with, which is greateconomy.

I do not limit myself to the mere details of construction, as they could be modified in various ways withoutl departing from the spirit of my invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. A metallic railway tie having a bed plate, a longitudinal flange turned up at one side of said bed plate, and a similar flange turned down at the other side only of said bed plate, substantially as described.

2. A metallic railway tie having a bed plate, a longitudinal flange turned up at one side of said bed plate,a similar flange turned down at the other side only of said bed plate, and a transverse support for the rails secured to said tie, substantially as described.

3. A metallic railway tie provided with a bed plate, a longitudinal ilange turned up at one side of said bed plate, a similar flange turned down at the opposite side only of said bed plate, in combination with an elastic transverse support for the rails, bolts or rivets for securing-said rail support-to the bed plate `and bolts for holding said .flexible Arail supports firmly togetherand Vinfengagement `with vsaid rail.

:4. Inn-a metallic railway tie :provided `with oneupward and one `downwa1'd-extending longitudinal flange only, in combination'with two (2) elastic S shaped supports forthe-rails,

support the rails `also'clamp and hold thesaid rrails against movement in any direction.

5. A metallic railway tie provided Awitha base or bedplate, an upwardY extending` longitudinal flange oranchorsecured-tothe-one side only of said bed plate, a downwardextend-` ing longitudinal `flange orlanchor secured to the opposite side of said bedplate, and anupward extending transverse .tlangeg ory anchor secured to said bed plate, .whereby` lateral movement is rendered less liable anditheentire ltie is held firmly in the ballast.

6. -A metallicl railway tie provided with 1a baseorbed plate, an upward extending lon. gitudinal flange or. anchor, securedto said bed plate at the one side thereof only, adownward extending longitudinal flange or anchor secured to said bed plate at theoppositeside thereof, an .upward `extending transverse tlange or anchor secured to said bed plate and a downward extending transverse flange or anchor secured to said bed plat-e, whereby lateral` movement isrendered less liable and the entire tie -is held firmly intheballast.

7,'A metallic 'railway tie provided witha base or bed plate, an upward extending longitudinal tia-nge or anchor, a downward extending longitudinal flange or anchor, and a horizontal extending longitudinal plate secured to said downward extending `flange, as and for the purpose specified.

In testimony whereof I aliix my signature in the presence of two witnesses.
